Notes:
1. Exceeding the input range by a significant margin may damage the units. For 5V input models the input voltage
should not exceed 11V, for 12V input models 22V, for 24V input units 40V, and for 48V models 80V.
Pin Connections
2. When measuring output ripple, it is recommended that an external 0.33 ”F ceramic capacitor be placed from the Pin Single Dual Pin Single Dual
+Vout pin to the -Vout pin for single output units and from each output to common for dual output units.
3. These units should not be operated with a load under the specified minimum. Operation at no-load will increase
2 -Vin -Vin 14 +Vout +Vout
ripple significantly and may cause damage to the unit. 3 NC -Vout 15 NC NC
4. These converters are specified for operation without external components. However, in some applications the 9 NC Common 16 -Vout Common
addition of input/output capacitors will enhance stability and reduce output ripple. Recommended values are:
10 NC NC 22 +Vin +Vin
Output Capacitor
Input 11 NC -Vout 23 +Vin +Vin

In applications requiring very low output noise levels, a simple LC filter should be effective.
5. It is recommended that a fuse be used on the input of a power supply for protection.
